Granite countertops are a stunning choice for any kitchen, but they can be a bit fussy when it comes to stains. Whether it’s a splash of red wine, a smudge of grease, or a stubborn coffee mark, dealing with stains on granite requires a careful touch to keep your surfaces looking pristine. The good news is that with the right approach, you can tackle these stains effectively without damaging your beautiful granite. From gentle cleaning solutions to simple home remedies, there are several methods you can try. Embark on a journey, on which Jireh Stone and Marble explores the best ways to remove stains and keep your granite countertops gleaming like new.
1. Identify the Stain Type
Granite countertops are highly valued for their durability and elegance, but they are not immune to staining. Understanding the nature of the stain is critical to determining the best approach for removal. Different types of stains can afflict granite, including oil-based stains, coffee and tea stains, wine stains, rust stains, and biological stains such as mold and mildew.
Each type of stain interacts differently with granite, so correctly identifying the stain is crucial for selecting an effective cleaning method and product. Misidentifying the stain can lead to inappropriate treatments that may not only be ineffective but could potentially cause further damage to the countertop.
2. Blot, Don’t Rub
When addressing a fresh stain on granite countertops, the first step is to blot, not rub. Blotting involves gently pressing a clean, dry cloth or paper towel against the stained area to absorb the liquid. This method is preferable to rubbing, which can spread the stain and push it deeper into the granite’s porous surface. Rubbing can also cause surface scratches, compounding the problem.
To blot effectively, use a clean cloth or paper towel. Avoid fabrics that might transfer dyes or lint onto the granite. Press down gently on the stain without applying excessive pressure, which helps absorb the liquid without further spreading it. If the cloth becomes saturated, switch to a fresh, dry one to continue blotting. This technique helps lift the stain from the surface, making it easier to clean and reducing the risk of permanent discoloration.
3. Make a Poultice
For more persistent stains, a poultice can be an effective solution. A poultice is a paste-like substance applied to the stain to draw it out from the granite. The ingredients and formulation of the poultice depend on the type of stain you are dealing with.
For oil-based stains, mix baking soda with water to form a thick paste. Spread the paste over the stain and cover it with plastic wrap. Secure the edges with tape and allow the poultice to sit for 24-48 hours. The baking soda will absorb the oil from the granite. For other types of stains, such as coffee, tea, or wine, you might use hydrogen peroxide mixed with a suitable powder. This combination can help lift these types of stains from the granite surface.
4. Apply the Poultice
Applying the poultice correctly is key to effective stain removal. Start by mixing the ingredients to create a paste with the consistency of thick yogurt. Apply a generous amount of the poultice directly over the stain, ensuring that it covers the entire affected area.
Leave the poultice in place for 24-48 hours, depending on the severity of the stain. After the time has elapsed, carefully remove the plastic wrap and the poultice. You may need to gently scrape off any remaining paste using a plastic or wooden spatula to avoid scratching the granite. Wipe the area with a clean, damp cloth to remove any residue from the poultice.
5. Use Granite Cleaner
After successfully removing the stain, it’s essential to clean the area with a granite-specific cleaner. Granite cleaners are formulated to be gentle on the stone while effectively removing any remaining residues or cleaning agents. Regular household cleaners or harsh chemicals can damage granite, stripping away its natural shine or potentially causing discoloration.

Apply the granite cleaner according to the manufacturer’s instructions. Typically, you will spray the cleaner directly onto the granite surface and wipe it with a soft cloth. This step helps to remove any remnants of the poultice or other cleaning agents and leaves the granite surface clean and polished. It also helps to maintain the granite’s natural luster and ensures that no cleaning residues are left behind.
6. Seal the Granite
Sealing granite countertops is a crucial preventative measure to protect against future staining. Granite is a porous stone, which means it can absorb liquids and potentially stain over time. A good sealant creates a protective barrier on the surface, making it more resistant to stains and easier to clean.
To seal granite, choose a high-quality granite sealer suitable for your countertop. Clean the granite thoroughly before applying the sealer, ensuring it is free from dust, dirt, and any residual cleaning products. Follow the sealer’s instructions for application, usually involving spraying or applying the sealer with a clean cloth. Allow the sealer to sit for the recommended time, then buff the surface to remove any excess.
7. Remove Oil-Based Stains
Oil-based stains on granite countertops can be particularly stubborn due to their ability to penetrate the porous surface. These stains are often caused by cooking oils, greasy foods, or even certain personal care products. To effectively remove oil-based stains, you’ll need a specific approach that targets the oil without harming the granite.
Start by making a poultice designed for oil-based stains. Mix a paste of baking soda and water, aiming for a thick consistency similar to that of yogurt. After successful stain removal, it’s important to clean the granite with a granite-specific cleaner to ensure no leftover residue from the poultice remains. Regular sealing of the granite will help prevent future oil-based stains and maintain the countertop’s appearance.
8. Remove Coffee and Tea Stains
Coffee and tea stains can leave noticeable discolorations on granite countertops, especially on lighter-colored stones. These stains are often reddish-brown and can be challenging to eliminate. To tackle coffee and tea stains effectively, follow these steps:
Begin by creating a poultice suitable for coffee and tea stains. Mix hydrogen peroxide with a powder such as baking soda or flour to form a thick paste. Apply the paste directly to the stained area, covering it completely. Hydrogen peroxide acts as a bleaching agent, helping to lighten the stain, while the powder aids in absorbing the stain from the granite.
If the stain persists, you may need to repeat the poultice application. Once the stain is removed, clean the granite with a granite-specific cleaner to ensure it is free from any residue. Regular sealing of the granite will help prevent future coffee and tea stains and maintain its pristine appearance.
9. Remove Wine Stains
Wine stains, particularly from red wine, can be particularly problematic on granite countertops, leaving behind deep, noticeable discolorations. To effectively remove wine stains, follow these steps:
Start by preparing a poultice specifically for wine stains. Mix hydrogen peroxide with a powder such as baking soda or flour to create a thick paste. Apply this paste to the stained area, ensuring it covers the entire stain. Hydrogen peroxide helps to break down the pigments in the wine, while the powder absorbs the stain from the granite.
If necessary, repeat the process until the stain is fully removed. After successful stain removal, clean the granite with a granite-specific cleaner to ensure there is no residue left. Regular sealing will help protect the granite from future wine stains and maintain its beauty.
10. Remove Rust Stains
Rust stains on granite countertops, caused by iron deposits or rusty objects, often appear as reddish-brown marks. These stains can be challenging to remove but can be effectively treated with the right approach.

To address rust stains, prepare a poultice using a rust remover or a mixture of lemon juice and baking soda. For a homemade option, combine lemon juice with a powder like baking soda to form a thick paste. Apply this paste generously over the rust stain, covering it completely. The lemon juice helps to dissolve the rust, while the baking soda absorbs the stain from the granite.
If the rust stain persists, you may need to repeat the process. After successful removal, clean the granite with a granite-specific cleaner and ensure the surface is properly sealed to prevent future rust stains.
11. Remove Biological Stains
Biological stains, such as mold and mildew, can cause unsightly dark patches on granite countertops. These stains are often due to organic growth and can be particularly challenging to clean. To effectively remove biological stains, follow these steps:
Create a poultice for biological stains using a mixture of hydrogen peroxide and a powder such as baking soda or flour. Hydrogen peroxide acts as a disinfectant and helps to break down the organic material causing the stain. Mix the ingredients to form a thick paste and apply it directly to the stained area.
If necessary, repeat the poultice application until the stain is fully removed. After successful stain removal, clean the granite with a granite-specific cleaner and ensure that the surface is properly sealed to prevent future biological growth.
12. Regular Maintenance and Cleaning
Regular maintenance and cleaning are essential for keeping granite countertops looking their best and preventing stains. Implementing a routine cleaning schedule and using the right products can significantly extend the life of your granite surfaces.
For everyday cleaning, use a granite-specific cleaner to avoid damaging the stone. Regularly wipe down the countertops with a clean, damp cloth and a small amount of the cleaner to remove spills, crumbs, and dirt. Avoid using harsh chemicals or abrasive scrubbing pads, as these can scratch the surface and strip away the protective sealant.
